IMPROVEMENT IN OVEN-PLATES FOR COOKlNG-STOVES.

The Schedule referred to in these Letters Patent and making part of the same.

I, WILLIAM (L- DAVIS, of Oinciimati, Hamilton county, Ohio, have invented a new and useful Oven- Plate for Cook-Stoves, of which the following is a specification.

.Ncinrc and Oly'ccts of the Invention.

This invention relates to that member of a cookstove commonly known asthe upper fiont-oven plate, or,in-0ther words,the plate that is interposed between the upper front partof the oven and the fire-chamber; and

Myimprovcment consists in the construction of a recessed plate, having'a rib on its upper surface for the retention of the oven-plate and flanges on its ends which fit into grooves in theside plates of the stove, the recess in the plate being filled with a refractory material, held' in position by conical bolts. General Description with reference to the Drawing.

I ignre l is a side spectivc view, showing themrious parts of my oven-plate in a detached condition. Figure 2 is a perspective view of the complete plate ready for insertion in the store. 1

Figure 3 is a horizontal section of the same. Figure 4 is a vertical section through a portion of the front part of a cook-stove, with the oven-plate in position and Figure 5is a vertical section showing a modification of my invention.

The ovenplate proper consists of a metallic frame, A, which is open in front, as at u, and closed atthe back, top, and bottom, and both ends, so as to form a pit or recess, B, for the reception of a tile or slab, (i,

that is com lOSOd of fire-clay soa r-stonc or any other suitable refractory material.

The tile O,'if that is used, is provided with one or more rearwardly-converging apertures, e, for the reception of conical bolts, 1), whose screw-threaded shanks (Z, after passing througln apertures a", in the backof the oven-plate, have engaged with them the nuts I l, by which the two members A U are united but if fire-clay is used, the recess may be filled without bolts being en'iployed.

Projecting upwardly from the frame A is a longitudinal rib, (1 against which the top-plate F of the oven rests, as shown in fig. I.

The ends of frame A are provided with flanges G G, which fit between lugs or engage in groovesin the side plates of the' stove, and thereby retain said frame in its proper place, and prevent ashes getting into the oven.

The slab G or filling H being composed of a material that will resist the action of the fire for a great length of time, acts as a protection to the plate A, and thereby prevent-s its burning out and becoming cracked and warped, and protects the oven-plate, instead of a fire-plate, as is now generally used for that purpose.

The tile being secured directly to the plate, without any intervening space between them, the oven is sufiicicn tl y guarded fiom intense heat at that part, and with a considerable saving of space and material, allowing a larger oven in astove of given capacity than where a space is left between the members A (J, or the tile is secured to an independent frame in front of said oven-platc1 The conical shape of bolts 1), when tile is used, insure the retention of the tile within its frame, no matter how much the exposed surface of the former may be worn away by the action of the fire. N

If tire-clay or other plastic refractory material, H, is used, the bolts will be found unnecessary to its retention. Spurs, projections, or flanges on the inside surface of the plate, as shown at I I, in fig. 5, will suffice to retain the protecting material.

In the drawing, the oven-plate is shown as having only one tile secured within it, but it is evident two or more may be employed, as circumstances may dietate. l

The plate A at B being entire, there no danger of exposing the oven to the direct rays and influx of ashes from the fire, even should the tile or filling from some accident become broken or lost.

It will be seen that this arrangementdispenses entirely with any special guard-plate, (fire-back,) such as is commonly interposed between the front oven-plateand the fire-chamber, and thus saves both expense land room of such guard-plate.

Claim.

I claim as my invention- I The recessed metallic frame A, provided witha longitudinal rib, a, for the retention of the oven-plate and flanges G G, fitting in grooves in the side plates of the stove, the recess in said metallic frame being illled with arefractory material, 0, held in position by conical bolts I) D, all arranged and constructed as setforth.

In testimony of which invention, I hereunto set my hand.
